The frequency at which a mechanical system
will vibrate freely. A pendulum, for example,
always oscillates at the same frequency when
set in motion. This natural frequency depends
upon the string's weight and tension. More
complicated systems, such as bridges, also
vibrate with a fixed natural frequency. If a
varying force with a frequency equal to the
natural frequency is applied to such an
object the vibrations can become violent, a
phenomenon known as resonance.
